Chapter 3 Configuring with the Command-Line Interface
Configuring Inverse Multiplexing for ATM Interfaces
Step 3
Router# ip routing
Router# appletalk routing
Router# ipx routing
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Step 4
Router(config)# interface atm 1/0
Router(config-if)#
Enter interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Step 5
Router(config-if)# ima clock line
Enter the transmit clock mode for the selected
ATM interface. The choices are internal, line, or
loop. The default is line.
Step 6
Router(config-if)# cablelength short 133
For T1 interfaces only, specify the cable length
(short or long) followed by the length in feet. You
can view the acceptable cable lengths by including
the ? option after the long or short commands.
Step 7
Router(config-if)# loopback local
Specify the loopback type for this ATM interface
by entering the loopback command followed by
one of the following: line, local, payload, remote.
You can view command descriptions by including
the ? option after the loopback command
.
Step 8
Router(config-if)# impedance 120-ohm
For E1 interfaces only, specify the impedance
value for this ATM interface by entering the
impedance command followed by one of the
following: 120-ohm, 75-ohm. You can view
command descriptions by including the ? option
after the impedance command.
Note Your response must match the physical
cable connected to the ATM port:
Enter 75 ohm for coaxial unbalanced
cable, or 120 ohm for twisted-pair
balanced cable.
A response of no impedance selects the
default of 120 ohm.
Step 9
Router(config-if)# no shutdown
Enable the ATM interface by canceling the
shutdown state.
Step 10
Router(config-if)# Ctrl-z
When you finish configuring interfaces, return to
enable mode.
